Hello, what is the best way for the assembly of the plunger frame rear springs?
Are there any instructions, tricks and tips or devices available for this purpose?
Thanks
Kurt

A minor improvement on this technique............
..........with no injuries. I made 2 sheetmetal plates with a slot to accomodate 1/4" all-thread(15"). Then I found or made 1/4" ID washers that will just barely fit through the upper and lower spindle holes(they are different sizes) the top washer being ferrous so that it can be removed with a pointy magnet. Washer on top of slotted plate on top, washer below slotted plate on bottom. Compress the whole mess from the bottom. Tip it into the bottom, then the top. Release pressure on top nut with deep socket, slide plates out carefully. Then completely loosen top nut. Remove top nut and washer with magnet. The rest will drop out the bottom. Drop spindle in. Worked like a charm first time with no loss of skin.
All dimensions rough. Tape on plate is PTFE to aid slipping out.

That's a nice twist
on the method. I must admit I was a bit scared when I did mine the first time (although when I did it again to strip for plating it seemed much easier!
Presumably you need to have one nut more or less flush with the studding to get it in? The studding and nuts will stop you pulling the whole thing out sideways when you slide out the slotted plates.

As I was saying..........
Yes, have the top nut more or less flush and tighten the lower nut to compress the assembly. No fear.

... in the Edgar Franks and Haycraft books. Basically, you need a long 1/4" threaded rod (an old rear brake rod will do) with appropriate half moon washers to compress the springs.
Briefly: remove the bottom bolt; slacken the top pinch bolt; withdraw the central rod upwards (the tricky bit); VERY CAREFULLY push the whole assembly sideways until you can get the threaded rod through then use nuts on it to compress the springs till the whole lot comes out.
The springs are very strong and compressed by a couple of inches or so when assembled so are very highly loaded and can do a lot of damage to fingers, eyes and other parts.
BTW just realised you said "assemble" so this may mean yours are already in bits but the same process applies.
